DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector, and more particularly to an electrical connector in which the direction of a connection cable on a plug is variable when a multi-pin connector is in contact.

[0002]

2. Description of the Related Art FIG. 6 is a view showing a conventional electric connector, and FIG. 6A is a perspective view showing a receptacle 35 through internal contacts 33A, 33B and 33C, and FIG. Is a perspective view of the plug 32. FIG. In this electrical connector, the contacts of the receptacle 35 and the pins of the plug 32 are 3
Has been split. Contact 33A of receptacle 35
33C are arranged in a row in a hollow cylindrical shape, and are connected to wiring (not shown). Pin 32A of plug 32
31C are also arranged in a line and connected to the wiring in the connection cable 30.

The pins 31A to 31C of the plug 32 are indicated by arrows 3
The receptacle 35 is inserted into the receptacle 35 from the direction 4 and the plug 32 is connected to the receptacle 35. Pins 31 </ b> A to 31 </ b> C which are insertion directions of plug 32 into receptacle 35
Is connected to the receptacle 35 at a right angle to the direction of the connector 35 and can rotate coaxially with the pins 31A to 31C with respect to the receptacle 35.
It can be changed up to 360 degrees.

[0004]

The problem with the conventional electrical connector is that when the plug 32 is inserted into the receptacle 35 and connected, the pins 31A to 31C of the plug 32 correspond to the contacts 33A to 33C of the receptacle 35. It comes into contact with things other than what you do.

The reason is that the pins 31A-3 of the plug 32
This is because 1C is inserted along the row of the contacts 33A to 33C arranged in one row of the receptacle 35.

For example, the pins 31A of the plug 32 should only contact the corresponding contacts 33A of the receptacle 35. However, when the plug 32 is inserted into the receptacle 35, the pins 31A are connected to the contacts 33C, 33B of the receptacle 35. The contacts 33A cannot be contacted until they come in contact one after another. That is, the pin 31A comes into contact with the contacts 33C and 33B which should not be in contact. Similarly, the pin 31B comes into contact with the contact 33C which should not be in contact.

[0007]

According to the present invention, there is provided an electric connector in which a contact of the receptacle contacts a pin of the plug when the plug is inserted into the receptacle. A rotating part rotatably attached to the fixed part, a connector fixed to the rotating part and the pin always in sliding contact,
A connection cable having wiring connected to the connector and attached to the rotating section.

According to the present invention, there is provided an electrical connector wherein a plurality of contacts of the receptacle come into contact with corresponding ones of a plurality of pins of the plug when the plug is inserted into the receptacle. A fixing portion of the plug, which is arranged and fixed at a different position on a plane orthogonal to the direction of insertion into the receptacle, and a rotating portion rotatably mounted on the fixing portion, each being fixed to the rotating portion. A plurality of connectors slidingly contacting the corresponding one of the pins at different positions in the direction of the rotation center axis of the rotating portion, and a plurality of wires each connected to the corresponding one of the plurality of connectors. And a connection cable attached to the rotating section.

[0009]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of an electrical connector according to an embodiment of the present invention, showing a state in which a plug 10 is connected to a receptacle 21. The plug 10 includes a fixed part 16 and a rotating part 23, and the connecting part 22 is connected to the rotating part 23.
Is attached. The wiring connected to the receptacle 21 is not shown. 2A is a longitudinal sectional view of the plug 10, and FIG. 2B is an AA sectional view of FIG. 2A. FIG. 3 is an exploded perspective view of the plug 10, and FIG. 3A shows a state in which the fixing portion 16 and the rotating portion 23 are cut along a plane passing through the central axis, and FIG. FIG. 3C shows pins 14 a to 14 c fixed to the fixing portion 16.

The rotating portion 23 has a hollow cylindrical shape with only one end closed, and an open end is slidably fitted into an annular groove of the fixed portion 16 and is rotatable with respect to the fixed portion 16. . The fixing portion 16 has a pin fixing portion 15 fixed in a hole provided in the center, and three pins 14 a to 14 c are inserted and fixed in the pin fixing portion 15, and the rear ends of the pins 14 a to 14 c It extends inside, and its tip protrudes outward from the pin fixing portion 15 and is connected to a contact (not shown) of the receptacle 21 when connecting the connector.

Each of three circumferential grooves provided on the inner surface of the rotating portion 23 has annular connectors 12a to 12 shown in FIG.
c is fixed and connected, and each of 12a to 12c is connected to a wiring 13a to 13c in the connection cable 22.
5 are fixed to the pins 14a to 14c, respectively, inside the rotating portion 23, and the contacts 11a to 11c are always in contact with the connectors 12a to 12c by the spring force. .

The connection cables 22 are connected to the connectors 12a to 12c from the wirings 13a to 13c, and are connected to the connectors 12a to 12c.
c to the connectors 11a to 11c.
a to 11c are connected to the pins 14a to 14c.

By inserting the plug 10 into the receptacle 21, the pins 14a to 14c are connected to the contacts on the receptacle 21 side.

The pins 14a to 14c are not arranged in the direction in which the plug 10 is inserted into the receptacle 21 (the center axis of the rotating part 23 and the directions of the pins 14a to 14c), but are separately located on a plane perpendicular to the direction of insertion. When the plug 10 is inserted into the receptacle 21, the pins 14 a to 14 c do not come into contact with contacts other than the corresponding ones of the receptacle 21.

The connecting cable 22 is connected to the rotating part 23 by the rotating part 2.
3 is attached in a direction perpendicular to the central axis, and the rotating part 23 is rotatable around the central axis.

[0017]

The first effect is that, even when a plurality of pins and contacts are provided for each of the plug and the receptacle, each pin does not come into contact with a contact other than the corresponding one when the plug is inserted into the receptacle. That is.

The reason is that the pins are arranged so as to be separately located on a plan view orthogonal to the insertion direction of the plug into the receptacle, and are not arranged in the insertion direction.

The second effect is that the direction of the connection cable can be changed. As a result, the user can use the electrical connection connector in an easy direction of the connection cable.

The reason is that the rotating part can be rotated to freely change the direction.

A third effect is that the types of plugs can be reduced. As a result, plugs can be produced at lower cost than before.

The reason is that it is not necessary to manufacture various plugs in which the direction of the connection cable differs with respect to the pin arrangement because the structure is such that the direction of the connection cable can be changed.
